VSCode中的JavaFX-11:错误:无法找到或加载主类Files \ Java \ javafx-sdk-11.0.2 \ lib [英] JavaFX-11 in VSCode: Error: Could not find or load main class Files\Java\javafx-sdk-11.0.2\lib

问题描述

我一直试图在Visual Studio Code中设置JavaFX-11.

I have been trying to set up JavaFX-11 in Visual Studio Code.

我发现了这篇帖子带有VSCode的JavaFX-11 ，其中介绍了如何执行此操作，并按照步骤操作.

I found this post JavaFX-11 with VSCode, which explained how to do so, and followed the steps.

但是，我需要通过在launch.json文件中添加vmArgs的条目来包括JavaFX SDK的模块路径:

However, I need to include the module-path to the JavaFX SDK by adding an entry for the vmArgs in the launch.json file:

{
"configurations": [
    {
        "type": "java",
        "name": "CodeLens (Launch) - Main",
        "request": "launch",
        "vmArgs": "--module-path C:\\Program Files\\Java\\javafx-sdk-11.0.2\\lib --add-modules javafx.controls,javafx.fxml",
        "mainClass": "hellofx.Main",
        "projectName": "hellofx"
    }
]

}

是我到JavaFX SDK的本地路径.但是，当我尝试运行程序时，出现以下错误:

As you can see in the vmArgs entry, is my local path to the JavaFX SDK. However, when I try to run the program I get the following error:

错误:找不到或加载主类 文件\ Java \ javafx-sdk-11.0.2 \ lib由以下原因引起: java.lang.ClassNotFoundException:Files \ Java \ javafx-sdk-11.0.2 \ lib

Error: Could not find or load main class Files\Java\javafx-sdk-11.0.2\lib Caused by: java.lang.ClassNotFoundException: Files\Java\javafx-sdk-11.0.2\lib

在过去的几个小时里，我试图弄清楚为什么它不起作用.我写的论点错了吗?我看到有.jmods文件.我应该下载那些文件吗?还有其他方法可以指定模块路径吗?

For the past hours I have trying to figure out why it doesn't work. Am I writing the arguments wrong? I saw there are .jmods files. Should I download those files? Is there any other way to specify the module path?

值得一提的是，我正在Windows 10中运行Visual Studio Code，因此我必须使用转义序列来使用反斜杠.

Is worth to mention that I am running Visual Studio Code in Windows 10, so I have to use escape sequence to use backslashes.

推荐答案

如您所发布的错误所示，您可以看到:

As you can see by the error you have posted:

错误:找不到或加载主类Files \ Java \ javafx-sdk-11.0.2 \ lib

Error: Could not find or load main class Files\Java\javafx-sdk-11.0.2\lib

很明显，问题与您在Program Files中的空间有关.

it is clear that the issue is related to the space you have in Program Files.

解决方案

作为一种可能的解决方案，您可以将JavaFX SDK移至路径中没有空格的文件夹，并相应地设置vmArgs，例如:

As a possible solution, you could move your JavaFX SDK to a folder without spaces in its path, and set your vmArgs accordingly, like:

"vmArgs": "--module-path C:\\Java\\javafx-sdk-11.0.2\\lib --add-modules javafx.controls,javafx.fxml",

虽然可行，但如果您仍然希望保留当前的方法，则必须找到一种方法来使用空格设置路径.

While that works, if you still want to keep your current approach, you have to find a way to set the path with spaces.

基于类似的问题，您会发现:

Based on a similar issue, you can find that:

包含空格的路径应用(转义的)双引号引起来

Paths containing spaces should be surrounded by (escaped) double quotes

因此，这将是您的解决方案:

So this will be the solution in your case:

"vmArgs": "--module-path \"C:\\Program Files\\Java\\javafx-sdk-11.0.2\\lib\" --add-modules javafx.controls,javafx.fxml",

请注意，这不适用于带有JavaFX jar的.classpath文件中添加的path，这将是这样的:

Note this doesn't apply to the path added in the .classpath file with the JavaFX jars, that will be like this:

<classpathentry kind="lib" path="C:\\Program Files\\Java\\javafx-sdk-11.0.2\\lib\\javafx.base.jar"/>
